[React] React.PureComponent
React.PureComponent
is similar to React.Component
. The difference between them is that React.Component
doesn’t implement shouldComponentUpdate()
, but React.PureComponent
implements it with a shallow prop and state comparison.
If your React component’s render()
function renders the same result given the same props and state, you can use React.PureComponent
for a performance boost in some cases.
// Component class PureCompnent extends React.Component { render() { return ( <div> <h1>{this.props.title}</h1> </div> ); } } // use <PureComponent title={'Awesome React'} />
